Module Organization

C-cell and R-cell logic modules are arranged into horizontal banks called Clusters, each of which contains two C-cells

and one R-cell in a C-R-C configuration.

Clusters are further organized into modules called SuperClusters for improved design efficiency and device

performance, as shown in Figure 1-3. Each SuperCluster is a two-wide grouping of Clusters.
